This invention relates to fastening means for mullions of window casings.

The mullion of such casings have heretofore been connected by nails alone that extend sub- 5 stantially parallel to the grain of the parts held.

In such construction, because the mullion casing, especially when exposed to the weather, there has been great tendency of such mullion casing, it being attached to the pulley stiles or blind stops, to separate from the sill, or conversely, and leave an ugly gap between the sill and the lower end of the mullion casing.

The principal object of my invention is to provide a simple and efiective fastening means to hold the mullion casing down, or the sill up, and prevent the formation of such a gap. 7

Other objects will appear from the disclosure herein.

The invention is embodied in the preferred construction herein shown and described, the feature of novelty being finally claimed.

In the accompanying drawing:

Figure 1 is a View in front elevation of a window casing having a mullion according to the 25 invention, said view being taken from the outer or weather side.

Fig. 2 is a horizontal sectional view on the line IIII Fig. 1, but on a magnified scale.

Fig. 3 is a Vertical sectional View on the line IIIIII Fig. 2, looking to the left.

In the views the character 5 designates the sill which, as usual, has an outward and downward slant at its upper surface with shoulders to stop the rise of water. At its lower side the sill has 35 the usual longitudinal plow or groove 5 for receiving the siding. 6, 6, designates pulley stiles or plain stiles having secured thereto parting stops 1, 1, blind stops 8, 8, and inside stops 9, 9. These stops form the usual channels for sliding window sash. Strips l0, l0, called inside reversible stops, are secured to the inner edge of the sill by nails H, l l. The opening between the strips I is to be covered with the inside trim (not shown). The character l2 designates the mul- 45 lion casing which closes the space between the pulley stiles at the exterior side of the casing.

The pulley stiles are secured to the sill by nails I3 driven through the sill into the lower ends of the stiles. Because these nails extend into the 50 stiles in the direction of the grain of the wood their holding power is not as great as when nails extend crosswise of the grain.

The mullion I2 is commonly fastened to the sills by nails l3 but when this is done there is nothing to prevent the pulley stiles and the mullion casing, due to varying weather conditions, from pulling from the sill and notwithstanding such nails I3. To toe nail the lower end of the mullion to the sill from the outer side makes an unsightly and unsatisfactory job.

To overcome the difficulty set forth I drill a hole [4 through the sill somewhat in rear of the seat of the mullion casing on the sill and in rear of the groove and pass through said hole the lower arm l5 of a suitably stout wire or metallic bar fastener, the upper end of which is bent and transversely sharpened horizontally toform preferably a horizontal broad spike at l5 that is driven into the wood to engage the inner side of the mullion casing crosswise of the grain of the wood. At about its middle the wire fastener has a bend l5 offsetting the lower portion of the fastener in order that the said portion shall enter and extend through said hole I4 without obstructing the siding groove 5 The said wire fastener is properly connected with the inner side of th mullion casing before the latter is applied and nailed to the blind stops. The lower portion of the fastener is made of sufficient length to extend through and beyond the hole in the sill so that the lower end thereof can be bent with a blow or blows of a hammer into clinching engagement with the lower sideof the sill and thereby firmly connecting the mullion casing with the sill, as indicated by full lines in Fig. 3. An advantage of the invention, aside from its principal function, is that the fastener is concealed in the finished construction.

The forms of the parts can be changed without departing from the gist of the invention as claimed.

What I claim is:

A device for holding a mullion seated on a sill the latter provided with a vertical hole therethrough offset from the seat of the mullion casing on the sill, said device consisting of a piece of rod of bendable metal having its upper portion bent to substantially a right angle to form a spike to engage the inner side of the mullion casing, said rod having near its middle an ofisetting bend to cause the lower portion of the rod to aline With said hole in the sill, the said lower portion of the rod being of such length as to extend through said hole and permit the bending thereof to engage the lower side of the sill.
